Overview

SHF(L)-175-1217 Four-way reversing valve is a super heavy‑duty ultra‑large‑capacity four‑way reversing valve purpose‑built for high‑tonnage commercial HVAC, large modular central air‑conditioning and high‑power air‑source heat pump systems. This model adopts maximized internal flow channels and oversized spool assembly to accommodate extremely high refrigerant mass flow, delivering reliable flow direction switching under maximum system load to complete cooling‑heating cycle inversion for year‑round temperature control. The thickened reinforced valve body structure improves burst pressure tolerance and structural rigidity, adapting to peak pressure surges generated by large modular units. It maintains stable performance under frequent heavy‑load impact and sharp load fluctuations, and supports multiple new‑generation low‑GWP eco‑friendly refrigerants. Advanced multi‑stage sealing design effectively suppresses internal leakage under high‑flow conditions. As a core switching component for high‑power HVAC installations, it sustains long‑time continuous operation and raises the whole‑system operational stability of large‑tonnage refrigeration‑heat pump equipment.

Key Features

Achieves automatic cooling‑heating cycle reversal by switching refrigerant flow direction for modular high‑power units
Maximized internal flow passages, designed for ultra‑high refrigerant mass flow of ultra‑large tonnage systems
Extra‑large dimension precision spool assembly, low pressure drop and smooth reversing without jamming
Thickened reinforced valve‑body construction, superior burst‑pressure resistance and structural rigidity
Multi‑level sealing structure, minimizes internal leakage under high‑mass‑flow operating conditions
Robust anti‑shock and anti‑fatigue structure, tolerates recurring heavy‑load impact from modular units
Fully compatible with conventional refrigerants and latest low‑GWP eco‑friendly refrigerants
Reliable performance facing extreme load swing and transient pressure spike of large‑size HVAC equipment
Broad operating temperature range, maintains consistent performance under harsh ambient temperature
Low reversing impulse noise, avoids pressure shock disturbance to downstream system components
Large‑size ODF copper welding ports, meets piping requirement for ultra‑large capacity units
Excellent fatigue resistance, supports long‑duration continuous operation and frequent mode conversion
